License to Work: A National Study of Burdens from Occupational Licensing

Backflow Prevention Assembly Tester

Highlights

Definition

Backflow prevention devices are needed on public water systems to contain contaminants from entering the public water system through back-siphonage or back-pressure of the water and contaminants. Backflow prevention assembly testers inspect containment devices, which include double-check valves and reduced pressure zone devices, to ensure that the devices meet the requirements of acceptable containment devices.

Summary

Seventeen states and the District of Columbia require licenses for backflow prevention assembly testers, and most require courses that take fewer than 10 days to complete, plus one or two exams and fees. Texas, the state with the most burdensome requirements, requires a 40-hour course as well as two years of experience in a water-related field. All licensed states except Wisconsin require either one or two exams.
